North Korea

State media said the plan would then be presented to the leader Kim Jong Un who will make a decision on whether to proceed.

The report cited a commander in the Korean People's Army who said the Hwasong-12 rockets will cross the skies of Japan and hit the sea 30 to 40 kilometres from Guam

"The Hwasong-12 rockets to be launched by the KPA (Korean People's Army) will cross the sky above Shimane, Hiroshima and Koichi Prefectures of Japan," the report said, citing General Kim Rak Gyom, commander of the Strategic Force of the KPA.

Writing on Twitter, he said he would not allow China to "do nothing" about the reclusive state.

His comments came a day after Pyongyang test-fired its second intercontinental ballistic missile (ICBM) in a month.

It later claimed the test proved that the entire US was within striking range of its weaponry.

On Saturday, two US B-1 bombers conducted exercises over the Korean peninsula with South Korean and Japanese planes.

North Korea returned Otto Warmbier, 22, to the US last week, saying he had been in a coma for a year and that it was acting on humanitarian grounds.

His parents said he had been subjected to "awful torturous mistreatment".

Mr Warmbier, who was jailed for trying to steal a propaganda sign from a hotel, did not regain consciousness.

Mr Trump said that a "lot of bad things happened" to Mr Warmbier, but added: "At least we got him home to be with his parents, where they were so happy to see him, even though he was in very tough condition."

The measures impose a travel ban and asset freeze on four entities and 14 officials, including the head of North Korea's overseas spying operations.

The council voted unanimously to back the sanctions after weeks of negotiations between the US and China.

Pyongyang has defied a UN resolution banning all nuclear and missile tests.

The sanctions resolution was adopted by the 15-member council on Friday.

Among the 14 North Korean officials is Cho Il-u, who leads Pyongyang's foreign espionage operations.

The move comes just days after North Korea demonstrated a significant leap forward in their missile program after launching a projectile that achieved "successful" controlled reentry into the Earth's lower atmosphere rather than falling back to the surface, according to a preliminary US intelligence analysis, two US officials tell CNN.

Speaking in China, Putin called for a peaceful solution to the ongoing tensions on the Korean peninsula, Russia's Sputnik news agency reported.

"I would like to confirm that we are categorically against the expansion of the club of nuclear states, including through the Korean Peninsula," Putin told reporters. "We are against it and consider it counterproductive, damaging, dangerous," he said.

But in comments that appeared aimed at the US, he said that "intimidating (North Korea) is unacceptable."

Security researchers have documented similarities between the WannaCry code and malware created by Lazarus group, a hacking operation that has been linked to North Korea. The code similarities were discovered by Google researcher Neel Mehta on Monday. Google declined to comment.

"Our military is closely monitoring for provocative movements by North Korea and is maintaining all readiness postures," a statement from the military said.

The missile, launched near the city of Kusong, flew 700 kilometers (435 miles), the South Korean military said. A US defense official confirmed that it flew that far, but said the US is still assessing what type of missile it was.

A second defense official told CNN: "At this point, we see nothing consistent with an (intercontinental ballistic missile) launch."

Kim is believed to be the fourth US citizen currently detained in North Korea.

In April, KCNA said Tony Kim -- also known as Kim Sang Duk -- was detained for "hostile acts" toward the North Korean regime.

Otto Warmbier, a University of Virginia student, was sentenced to 15 years of hard labor in 2016 for removing a political sign.

And Kim Dong Chul, the president of a company involved in international trade and hotel services, was arrested in 2015 and is serving 10 years on espionage charges.

At the same time, the Pentagon is trying to lower its public profile regarding Navy ship transits through the South China Sea, which have provoked Chinese ire, as part of an overall administration effort to improve relations with Beijing so that it pressures Pyongyang to curb its nuclear weapons program.

The strategy comes in the wake of contradictory statements by President Donald Trump on his policy toward North Korea and growing tensions in the region over its nuclear and ballistic missile capabilities.
